How to reconstitute Epitalon
Epitalon is sold as a freeze-dried powder, most often in 10 mg, 20 mg, 50 mg vials. Add bacteriostatic water, let it dissolve without shaking, and the concentration is the vial amount divided by the water: 10 mg in 2 mL is 5 mg/mL. On a U-100 insulin syringe one unit is 0.01 mL, so each unit carries 50 mcg, and a 5 mg dose is 100 units.
Not approved for human use. Commonly cited: 5 to 10 mg daily for 10 to 20 days. Nothing on this page is a dosing recommendation; the calculator converts a dose you already have into syringe units.
Epitalon doses in syringe units (10 mg vial, 2 mL water)
| Dose | Units | mL | Doses per vial |
|---|---|---|---|
| 5 mg | 100 | 1 | 2 |
| 10 mg | 200 | 2 | 1 |
Vial sizes at 5 mg per dose
| Vial | Water | Concentration | Units per dose | Doses |
|---|---|---|---|---|
| 10 mg | 2 mL | 5 mg/mL | 100 | 2 |
| 20 mg | 2 mL | 10 mg/mL | 50 | 4 |
| 50 mg | 2 mL | 25 mg/mL | 20 | 10 |
The dose column is in mg. Doubling the water halves the concentration and doubles the units per dose; the number of doses in the vial never changes. If a dose comes out under 5 units, use less water so it is easier to measure. If it exceeds the syringe, use more water or a bigger syringe.
Worked example
10 mg / 2 mL = 5 mg/mL = 5,000 mcg/mL. One unit = 0.01 mL = 50 mcg. 5,000 mcg / 50 mcg per unit = 100 units. The vial holds 10,000 / 5,000 = 2 doses, which at 7 per week is about 2 days.
